ENVELOP.

To all whom it may concern: I

Be it known that I, JENNIE M. LONGER- EON, a citizen of the United States, residing at Gantrall, inthe'county ofSangamon and State of Illinois, have invented a new and useful Envelop; and I do hereby declare the following to be a full, clear,.and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improved envelop, and an object of the invention is to provide an envelop having a reinforcing seam through the bottom flap and extending through the address portion of the envelop transversely and through the closure flap for strengthening and bracing the envelop, said reinforcing means terminating in a stiffened tongue to overlie the seam between the two end flaps, and overlie the lower edge of the envelop and a portion of the address face of the envelop, to hold the seam between the two end'flaps secure.

Another object of the invention is the provision of a transverse tab at the end of the tongue, on which the return address of the writer may be printed, and on a part of the tongue the monogram may be stamped or otherwise afiixed thereto.

In practical fields the details of construction may necessitate alterations, falling within the scope of what is claimed.

The invention comprises further features and combination of parts, as hereinafter set forth, shown in the drawings and claimed.

In the drawings: Figure 1 is a view in perspective showing the blank of the envelop with the bottom flap partially open, and the two end flaps and the closure flap entirely open. Fig. 2 is a view in perspecclosed. Fig. 3 is a sectional view on line 83 of Fig. 2. Fig. 4 is a sectional view on line H of Fig. 2. Fig. 5 is a perspective view of an envelop showing a modified structure, which blank is in one piece with the tongue thereof provided with a trans verse tab, and showing the flaps opened. Fig. 6 is a view in perspective of the envelop constructed from a blank shown in Fig. 5, illustrating the various flaps closed.

Fig. 7 is a longitudinal sectional view on line 77 of Fig. 6. Fig. 8 is a transverse sectional view on line 8-8 of Fig. 6.

Referring to Figs. 1 to 4: inclusive it is to be observed that the blank of the en- Specification ofLetters Patent. Pate t 21 9 5 Application filed. August 2, 1915. Serial no. 43,154..

the transverse edge portions 4L and 5 of 'which two sections or parts 2 and 3 of the blank '1 overlap each other as shown, and are secured together by adhesive material, thereby providing a reinforcing means 6 extending transversely of the blank and the bottom and closure flaps 7 and 8. The reinforcing means 6 for its full width extends beyond the closure flap thereby forming a stiffened tongue 9. The closure flap 8 adjacent its angular edges upon its inner face, and the inner face of the tongue 9 are provided with suitable adhesive material 10 and 11. The entire outer face of the bottom flap is provided with adhesive material 12, so that after the bottom flap is closed the end flaps 13 and 1 1 may be secured to the bottom flap by the adhesive material 12. The end flap 13 adjacent its end edge is provided with adhesive material 15, so as to overlie and be secured to the end flap 14 adjacent its end edge, thereby forming a seam between the end fiap, which seam is covered by the closure flap and the tongue 9, the extremity of which from the dotted line 16 to its extreme edge is-bent over the lower edge of the envelop and secured to the portion of the address face of the envelop, that vis when sealing-the closure flap. That portion ofthe tongue 9 beyond the dotted line 16 is designed to contain a monogram or a coat of arms or the like if desired.

The construction of envelop disclosed in Figs. 5 to 8 inclusive is substantially the same as that illustrated in Figs. 1 to 4 inclusive with the exception, however, that. the blank is constructed of a single piece, and with the exception that the tongue 9 is a trifle longer than that shown in Fig. 1 and terminating in a transverse tab 18,. which is secured to the address face of the envelop, as shown in Fig. 6 so as to receive the return address of the sender of a'letter in an envelop of this character.

The invention having been set forth, what is claimed as new and useful is I An envelop, comprising a blank having a bottom flap, the entire outer surface of which has adhesive material thereon, an address portion, two end fiaps to be secured to the entire outer face of the bottom flap by said adhesive material, one of said end flaps having adhesive material adjacent its end edge and designed to overlie and be secured adjacent the end edge of the opposite end flap. forming a seam, a closure flap opposite the bottom flap to be secured to the outerfaces of the end flaps and having a tongue overlying the'seam of the end flaps with its end portion bent over the lower edge of the together by the adhesive material forini'ng-a Copies of this iate'nt may be obtained for five-cents each, by addressing .the Commissioner of Patents,

reinforcing seam, extensions of which portions form the tongue of the closure flap, 7

said tongue having atr'ansverse tab to re- 7 ceive a return address.

In testimony whereof I havesigned my name to this specification in the presence of two subscribing witnesses.
